PORTABLE ELECTRIC SAFETY-LAMP.

Specification of Letters Patent.

Patented July 29, 1913.

Application led December 9, 1912. Serial No. 735,770.

To all whom it may concern.'

Be it known that I, EMIL. BANICK, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Portable Electric Safety-Lamps, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in portable electric safety lamps, the object of the invention being to provide a handy, safe and convenient article for the purpose and which is particularly applicable for use in dangerous situations such as coal or other mines, powder mills, magazines, chemical laboratories and the like.

Another object ofthe invention is to provide-` an electric safety 'lamp of the above character which will possess advantages in points of eiciencyand durability, is inexpensive tol manufacturevand at the same time is simple in construction and operation. f Y

lith the above and other objects in View, the invention consists inthe novel features of construction and combination and 'ari rangement of parts hereinafter more fully described, pointed out in theA claims, and shown in the accompanying drawing, in which Figure 1 is a front elevation of an electric safety lamp constructed in accordance with my invention, parts being broken'awayand in section. Fig. 2 is a transverse sectional view. Fig. 3 is a vertical sectional view through the casing. Fig. 4 is a vertical sectional view through the entire device, and Fig. 5 is a detail vertical sectional view illustrating the construction of the valve.

Referring more particularly to the drawings, 1 indicates the case or receptacle which is provided with a suitable handle 2 whereby the same may be readily transported from place to place. Arranged within the casing 1 is a battery 3 which is spaced from the front wall of the ease by means of blocks 4 arranged at the top and bottom of the battery and dis osed between the battery and the front wa l of the casing. Secured to the battery casing and projecting upwardly therefrom are the supporting members 5 which are adapted to support the binding posts 6. Arranged within the casing and disposed between the battery and the front wall of the casing is an angular guard plate 7. Secured to the front wall of the casing upon the inner side thereof and having their inner ends overlapping, within the angular guard plate 7, are the contact plates 8 and 9, said plates beine suit-ably connected to the binding posts 6 by the positive and negative wires 10 and 11.

Mounted in the front wall of the casing and arranged just above the guard plate 7 is a lamp socket 12, in which is arranged the incandescent lamp 13. The socket 12 is suitably .connected to the contact plates through. the medium of the negative wire 11. Secured to the front wall of the casing and arranged around the lamp 13 is a refiector 14, and slidably mounted within an opening of. the reiector at the lower side thereof, is a rodl, the inner end of which is disposed through an opening in the front wall of the casing and adapted to engage the free ends of the contact plates 8 and 9 :when the glass 16 isarranged in the front of the reector, thus closing the circuit. Tt will be apparent that by having the rod 15 slidably mounted and the inner end thereof engaging the overlapping ends of the con- -tact plates, that when the glass 16 is placed within the front of the reflector 14, it will press inwardly upon the rod 15 and engage the innervends of the contact plates so that the circuit will be closed, but in case the glass should be broken, the resiliency of the plates will force the rod outwardly, thus disengaging the overlapping ends of the contact plates and opening the circuit to extinguish the lamp. Thus it will be seen that shouldy there be any explosive gases within the room, or any danger of any explosive material coming in contact with the light, the danger of an explosion will be eliminated by the instantaneous extinguishing of the lamp.

The upper end of the battery casing is provided with a suitable opening in which is arranged a vent pipe 17, and slidably mounted within the vent pipe is a stem 18, the lower end of which is secured to the circular valve member 19. It will be apparent that should the valve casing be tipped at an angle or upside down, the upper end of the valve 19 will be disposed within the'lower end of the pipe 17 to prevent any escape of the electro yte. It will also be seen that when the electrolyte becomes low within the battery casing, the height thereof within the casing will be indicated by the stem 18.

upwardly' through the e neet-ionA with the accompanying drawings, it will be apparent that I'have provided a, simple and durable electric .safety lamp which'can .be easily transported from place. to place and at the same time is simple in construction and' inexpensive to manufacture. Y A Q i In the operation ofmy improved safety lamp, the rod' 15 is-mounted within the openings in the reflector and the front wall of. the casing and Yhas its inner end coming in Contact vwith the free end of the plate 9.

The rod is then pressed inwardly until the 4plate 9 engages the :tree end of the plate .8. The glass lis then arranged within the reflector so that the same' may be pressed against the o uter endv of the rod retaining the same in its operative position so as to keep the circuitvclosed and the 4lamp 13 lighted. Ifthe reflector glass is accidentally broken, the resiliency of the plate 9 will push the rod 15 outwardly, thus disengaging the plates 8 and 9 and breaking the circuit which will immediately extinguish the lamp before the obstruction which broke the glass can reach the lamp to break it also. Thusb'y-the time the lamp is broken, all danger of ignition ot explosive material will be obviated'. It 'will be understood that the glass 16 maybe a frosted one for diffusing light in order to light up a given inclos'ed space, butif the light is to be used for revealing objects in the distance, a clear glass is used.A

. Wrhile I have shown and `described the preferred form ot' my invention, it vwill be obvious that Avarious changes in t-he details of construction and pro-portion may be resorted to for successfully carrying my invention into practice without sacrificing any of the novel features or departing from .the scope thereof.

IThat I claim is l. In a device ot the character described', the combination of acasing, a battery arranged within saidA casing and 'a lamp mounted in the front wall of the casing, a reflector surrounding said lamp and glass mounted in the front of the reiiector, resilient contact plates mounted' in the casing, a horizontally disposed rod slidably mounted in the front of the casing and pressed inwardlyby the glassin the reflector to normally retain the contact plates in an operative position to close the circuit between the lampand the battery, whereby when the glass is broken the contact plates will be released to break the circuit between the lamp and the battery. R

2. Ina device of the character described,

the combination of a casing, a battery ar-A ranged' within said casing, a lamp mounted in the front wall of thecasing, overlapped resilient contact plates within the casing, connections between the battery and the Contact' plates, connections between the contact plates and the lamp, a stationary reflector ,surrounding the lamp, a destructi ble member in front of the reflector, and means engaged with the destructible niember and with one of the contact plates to retain the -lll-tter in lengagement with the other contact plate and thereby close the circuit while the destructible member is in position. Y

Y3. In a device of the character described,

the combination of a casing, a battery arranged wit-hin the casing, overlapped resilient contact plates, 'connections between the battery plates, a lamp mounted in one wall of the casing, a reflector surrounding the the combination of'a casing, a battery within the casing, a stationary lamp mounted in the casing, a stationary'reflector around the lamp, a destruct-ible member outwardly of the reflector, a pair of normally spaced apart resilient contact plates within the casing, connections between the battery and the contact plates, connections between the contact plates and the lamp, and a slidable horizontal rod for forcing oneof the contact plates against the other plate to complete the circuit, nsaid rod being retained in position by the destructible' member, whereby said rod will be -torced outwardly by the Contact plates, upon destruction of the destruct-ible member.
